[tom burkart]

Quoting Anthony Dunne <agdunne at hotmail.com>:

> Firstly would this work?
Yes.

> Secondly, my dilemma is the pin-out.
> I believe on the DB9 pin 1 is DCD (the actual pulse) and pin 5 is  
> the ground. Is this correct?
Yes.

> Could I use a cable such as this:-
No.

> Alternatively, is there a simpler way to achieve the goal?
No, you really need a level shifting stage that converts the PPS to  
RS232 levels.
